how do you 'almost go into a coma'?
Not take in enough carbs with your insulin....or something else I'm not aware of., because i did exactly what you are supposed to. Don't know if "coma" is accurate...I'm using it for effect...but it's not a pleasant experience. Face goes numb, sweating profusely..( like DRENCHED in sweat from head to toe)...chills, sweats...and you just want to go to sleep, as in you can't keep your eyes open. It's scary. I did insulin for a week...won't fuck with it ever again.
PS...it's "almost" because as soon as it starts happening, you start wacking down Sugar packets and it stops after 20 minutes or so.
